1986 Our offices were originally located in Honolulu, Hawaii, where we developed the SeaMARC/S 150 kHz bathymetric side-scan mapping system and associated processing and mapping software. SeaMARC/S was the first commercially available seafloor mapping system to provide simultaneous, co-registered sonar imagery and swath bathymetry. We then built a deep ocean swath mapping system, the 12 kHz IZANAGI, for the University of Tokyo. The IZANGI operates in any water depth, providing swath bathymetry and side-scan images up to 10 kilometers wide.

1988 SSI completed the first of four Sys120 high-resolution bathymetric side-scans for surveys to 1,200 meters water depth.

1990 We created a low frequency mapping system, the Sys09 which maps any ocean depth with swath widths as great as 10 kilometers while being towed at speeds of up to 9 knots. Operating at 9 kHz, the Sys09 delivers very high coverage rates with excellent side-scan and swath bathymetry resolution. A second Sys09 was built in 1992.

1994 We introduced two Sys100 towed swath bathymetric side-scan systems, incorporating a 3.5 to 6.5 kHz chirp subbottom profiler, improved transducer design, and an advanced six-component attitude sensor (roll, pitch, heading, and heave as well as longitudinal and transverse displacement). We designed this new mapping system to operate at speeds of up to 6 knots and to map in water depths down to 1,300 meters.

1997 SSI delivered a complete Sys09 to the Maritime Safety Agency of Japan for installation on the research vessel SHOYO, the new state-of-the-art flagship of MSA.

1998 SSI engineers completed the Sys100D, which extended Sys100 capabilities to 2,500 meters water depth.

1999 The University of Tokyo receives the first full ocean depth (6,000 meters) capable Sys100D system developed and delivered by SSI .

2005 FSSI begins the integration of an Autonomous Underwater Vehicle (AUV)
